'To all whom it may concern: v

Be it known that we, FRANK L. Dian, a citizen of the United States, residing at Montclair, in the county of Essex and State of New Jersey, and FRANK D. Lnwis. a citi zen of the United States, and a resident of Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Phonograph- Reproducers, of which the following is adescription.

Our invention relates to phonograph re object the production of a reproducer having two stylus-es carried by a single lever, said leverbeing pivoted to a support which is carried by a floating weight and capable of being moved with respect thereto so as to bring either of said styluses into and out of operative positionwith respect to the record surface, and said Styluses being adapted to operate upon phonograph records of different pitch; for example, one stylus may be suitable for operating upon records having one hundred turns or threads per inch and the other stylusmay besuitable for vrecords having two hundred threads per inch. Indicating means are also provided for designating which of the Styluses is in operative position.

In order that the invention may be more fully understood, reference is inade to the accompanying drawing, of which Figure 1 is a side elevation, partly 111 sec- 1 tion, of a reproducer constructed in accordance with our invention, and Fig. 2 a bottom plan viewof the same.

The rcproducer shown comprises a body 1, within which the diaphragm 2 is secured in the usual manner by and the floating weight 4 is pivoted at 5 to the block 6 carried by the body 1'. The floating weight 4 is formed with a central opening 7 and recess 8, within which is situated the stylus lever support which may be in the form of a flanged sleeve or bushing 9. The upper end of said bushing is threaded to receive the nut 10 which presses a spring washer or dished plate 11 against the upper surface of theiioating weight, so as to hold the sup ort 9 in frictional engagement with the -sai weight.- The support 9 is formed withaa pair of depending lugs 12 which receive the pin 13 upon which the stylus lever the clamping ring 3f 1i pivoted. Said lever 14 is shaped somiwxhat like the letter T and at the extremity of each end of the cross-arm is a socket in which are secured the'styluses 15 It and 16, the former being adapted to operate i upon a record having two hundred threads per inch and the latter upon records having one hundredthreadsper inch. The opposite end of the lever 14 is connected to the link 17, the upper end of which is connected l I to the eye 18 secured to the center of the diaphragm 2. l

There is an index finger or plate 19, which is provided at one end with a pin EZO engaging an opening in the support 9 and with a holding screw 21 passing through an opening in the plate 19 and is threaded in the flange of the bushing 9. The plate 19 cooperates with indicia 22 applied to the lower surface of the floating weight eito'designate which of the styl-useslfi and 16 is in operative position, and it also limits the angular movement of the bushing 9 by cooperation with the stop pins 23 which extend downward from the weight 4.

Vhen the parts are in the position of Fig. 2,-the stylus 15 is in operative position with respect tothe record surface and the index finger 19 is opposite the numerals 200 indicating that the reproduce'r is in suitable position for operating upon records having two hundred threads per inch. In order to 0011- vert itinto a reproducer suitable for records having one hundred threads per inch it is necessary only to move the bushing S) into its other extreme position, at which time the finger 19 will be opposite the numerals CC ,7.

Having now described our invention. what we claim is: i

1. In a phonograph reproducer, the combination of the body and vibratory means carried thereby, the floating weight, a stylus lever support movable with respect to said weight, a stylus le'ver pivoted to said support and a pair of reproducer Styluses of different diameters 'carried-by said stylus lever. I substantially as set forth.

2. In a phonograph reproducer, the combination of the body and vibratory means,

the floating wei ht, a stylus lever support capable of angufii'r adjustment with respect i to said weight, a stylus lever pivoted to said support and a pair of reproducer Styluses of different diameters carried by said lever, substantially as set forth.

3. In a phonograph reproducer, the combination of the body and vibratory means, the floating weight, a stylus lever support capable of angular adjustment with respect to said Weight, a stylus lever pivoted to said support and a pair of reproducer styluses of di erent diameters carried by said lever, said styluses being applied to the same end of said lever, the opposite end of said lever being connected to said vibratory means, sub stantially as set forth.

4. In a phonograph reproducer, the combination of the body and vibratory means carried thereby, the floating weight, a stylus lever support movable with respect to said weight, a stylus lever pivoted to said support, a pair of reproducer styluses of different diameters carried. by said stylus lever, and'indicating means for designating the operative positions of said styluses, substantially as set forth.

5. In a phonograph reproducer, the combination of the body and vibratory means, the floating weight, a stylus lever support capable of angular adjustment with respect to said Weight, a stylus lever pivoted to said support, a pair of reproducer styluses of dif ferent diameters carried by said lever, said styluses being applied to the same end of said lever and the opposite end of said lever being connected to said vibratory means, and indicating means for designating the operative positions of said Styluses, substantially as set forth.

6. In a phonograph reproducer, the combination of the floating weight, the fulcrum pivoted to said weight, and a stylus lever carried by said weight, a stylus lever provided with a plurality of styluse's and pivotsaid fulcrum being piv-' ed to said fulcrum, otally mounted upon said weight and fric tionally held thereto, substantially as set forth. I

8. In a phonograph reproducer, the combination of the floating weight, a fulcrum pivoted to said weight, a stylus lever provided with a pair of Styluses. and pivoted to said fulcrum, and indicating means for designating both operative positions of said stylus lever, substantially as set forth.

9. In a phonograph reproducer, the combination of the body, floating weight, a support pivoted to said floating weight, a stylus lever pivoted to said support, and a pair of Styluses carried by said lever, substantially as set forth.

10. In a phonograph reproducer, the combination of the body, port pivoted to said lever pivoted to said support, a pair of styluses carried by said lever, and ineansfor limiting the angular movement of said stylus lever support, substantially as set forth.
